在Java Swing中設置較小的按鈕大小

Question

我想在Java Swing中實現一個GUI;但我被困在按鈕尺寸上，我試圖縮小尺寸。我試圖使用setSize,setPrefferedSize和setmaximumSize，但沒有任何工作。有任何想法嗎？

import java.awt.*; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import javax.swing.JFrame; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import java.util.ArrayList; 
import java.util.HashMap; 
import javax.swing.JButton; 
import javax.swing.JScrollPane; 
import javax.swing.JTextField; 
import javax.swing.*; 
import javax.swing.border.Border; 

public class WorkStationGUI extends JFrame implements ActionListener { 

    JButton Worker1Process1; 
    JButton Worker1Process2; 
    JButton StopWorking; 
    // JScrollPane scrollList; 
    JTextArea OrderList; 
    JTextArea ProductList; 
    JTextField orders; 
    JTextField products; 
    JTextField Worker1; 
    JTextField Worker2; 
    private HashMap<String, Order> OrdersList; 
    private HashMap<String, Product> ProductsList; 

    public WorkStationGUI(HashMap<String, Order> orders, HashMap<String, Product> Products) { 
     this.OrdersList = orders; 
     this.ProductsList = Products; 
     setTitle("Work Station"); 
     setupEastandWest(); 
     setupSouthPanel(); 
     pack(); 
     setVisible(true); 
    } 

    private JLabel createOneLabel(String s, Color c) { 
     Font f = new Font(Font.SANS_SERIF, Font.BOLD, 18); 
     JLabel label = new JLabel(s, JLabel.CENTER); 
     label.setFont(f); 
     label.setBackground(c); 
     label.setOpaque(true); 
     return label; 
    } 

    private void setupEastandWest() { 

     // search panel contains label, text field and button 
     JPanel Panel = new JPanel(); 
     Worker1Process1 = new JButton("Worker 1"); 

     Worker1Process1.setPreferredSize(new Dimension(10, 10)); 

     Panel.add(Worker1Process1); 
     Worker1 = new JTextField(20); 
     Worker1Process1.setPreferredSize(new Dimension(90, 90)); 
     Worker1.setFont(new Font(Font.MONOSPACED, Font.PLAIN, 14)); 
     Worker1.setEditable(false); 
     Panel.setLayout(new GridLayout(2, 1)); 
     Panel.add(Worker1); 
     JPanel Panel2 = new JPanel(); 
     Worker1Process2 = new JButton("Worker 2"); 
     Panel2.add(Worker1Process2); 
     Worker2 = new JTextField(20); 
     Worker2.setFont(new Font(Font.MONOSPACED, Font.PLAIN, 14)); 
     Worker2.setEditable(false); 
     Panel2.setLayout(new GridLayout(2, 1)); 
     Panel2.add(Worker2);    

     Panel.setLayout(new GridLayout(2, 2)); 
     this.add(Panel, BorderLayout.EAST); 
     this.add(Panel2, BorderLayout.WEST); 
     // this.add(Panel2, BorderLayout.SOUTH); 
    } 

    private void setupSouthPanel() { 
     JPanel Panel = new JPanel(); 

     orders = new JTextField(1); 
     orders.setBackground(Color.LIGHT_GRAY); 
     Panel.add(orders); 
     JPanel Panel2 = new JPanel(); 
     products = new JTextField(1); 
     Panel.add(products); 
     products.setBackground(Color.LIGHT_GRAY); 
     Panel.setLayout(new GridLayout(2, 2)); 
     this.add(Panel, BorderLayout.CENTER); 
     this.add(Panel2, BorderLayout.SOUTH); 
    } 

    public void actionPerformed(ActionEvent e) { 
    } 
}

您正在使用GridLayout，它將使組件佔用所有相對於網格的容器空間。這不是真正的按鈕的最佳選擇。您可以嘗試使用FlowLayout或GridBagLayout。

此外，您正在設置佈局管理器後，您在面板上設置JButton。
